The present invention relates to an internal pressure relieving device for anti-armour ammunition. Said device is mainly adapted for use with barrel-loaded ammunition per se, that is a naked round comprising a cartridge case (2), which normally would be located in its packaging. A plurality of slot formed openings (8) has been cut out through a wall (4) of said cartridge case (2) and said openings as been sealed by means of inserts (12) of polymeric plastic introduced with a tight fit into each opening (8). Hence, by means of the characteristics of the plastic material, said inserts (12) can be configured to open up at a predetermined level of temperature (t 1 ). Alternatively, the inserts open up at a predetermined level of pressure (p 1 ) in the cartridge case.
